Objective:The study is to compare the prevalence and related factors of suicidal ideation in ado-lescents between China and Philippine.Methods:Our research data was downloaded from the website of world health organization (WHO).It was the data of China and Philippine from the Global school-based student health survey(GSHS)which was launched by the WHO,and 9173 students in China and 7338 students in Philippine aged 11 -16 years were involved.The situations of being serious injury,being bullied,sense of loneliness,insomnia, sense of hopelessness,friends,smoking,alcohol consumption,drug abuse and exercise were assessed by the ques-tionnaire.The definition of suicidal ideation was that ever thinking of suicide seriously in the last 12 months.Results:The rate of having suicidal ideation in China and Philippine were 17.4% (1544 /8881 )and 19.3% (1371 /7089),respectively.Multivariate analysis showed that female (OR =1.45),grade two and three of middle school (OR =1.29,1.43),being serious injury (OR =1.35),being bullied (OR =1.87),sense of loneliness (OR =1.47),insomnia (OR =1.55),sense of hopelessness (OR =3.36),alcohol consumption (OR =1.45)and drug abuse (OR =1.55)were the risk factors to suicidal ideation in China adolescents,and having good friends (OR=0.66)and exercise regularly (OR =0.78)were the protective factors.However,the female,grade,sense of lone-liness,insomnia and drug abuse were not the risk factors to suicidal ideation in Philippine adolescents,and other fac-tors were similar to China sample.Conclusion:There may be differences in the prevalence rate of suicidal ideation between adolescents in China and Philippine,with lower rate in China.Meanwhile,there are similarities in the relat-ed factors on the adolescent suicidal ideation of the two countries,with more risk factors in China sample.Therefore,the individualized targeted measures should be taken to prevent suicide in China and Philippine respectively.

Objective To analyze the related factors of obstructive sleep apnea syndrome (OSAS) in type 2 diabetes mellitus (T2DM) patients. Methods 289 participants were enrolled and 254 people finished the whole process. Portable sleep monitor was used to detect the breath situation during sleep , and related factors were also analyzed. Finally , 183 subjects were diagnosed as OSAS and 71 subjects were not. Results 254 T2DM subjects were enrolled, with 108 males (59%) and 183 participants were diagnosed as OSAS (72%). OSAS group had a higher diabetic duration,body mass index, 2 h plasma glucose,fasting insulin, C peptide level, systolic blood pressure, triglyceride, low density lipoprotein cholesterol, and homocysteine levels(P<0.01). The prevalences of dyslipidemia , hyperuricemia , high blood pressure , non-alcoholic fatty liver disease and metabolic syndromein OSAS group were also higher than that in compared groups. Logistic regression analysis showed that body mass index, dyslipidemia and high homocysteine level were independent risk factors of OSAS. Conclusions The prevalence of OSAS in T2DM was higher. Blood glucose level , body mass index and multiple metabolic parameters in OSAS patients elevated significantly. Obesity and insulin resistance were major factors during the process of the disease.

Objective To analyze the clinical features of infantile cytomegalovirus(CMV) hepatitis with cholestasis and investigate intrahepatic cholestasis due to hepatocytic impairment caused by CMV infection.Methods Forty-seven children with CMV cholestatic he-patitis were divided into 2 groups according to the level of total bilirubin(TB):22 cases with serum TB lower than 136.8 ?mol/L(groupⅠ),and 25 cases with serum TB higher than 136.8 ?mol/L(groupⅡ).All children were treated with both gangciclovir and routine met-hods,and serum biochemistry were checked before and after treatment.SPSS 13.0 software was used to analyze the data.Results Forty-seven cases of infantile CMV cholestatic hepatitis had different degrees of jaundice,hepatosplenomegaly and abnormal liver functions.The differences of serum ALT and AST between the 2 groups had statistical significance,the levels of serum gamma glutamy transferase(GGT) and alkaline phosphatase(ALP) were lightly higher in groupⅡcompared with those in groupⅠ,but there were no statistical significance.TB,direct bilirubin(DB),ALT and AST were decreased in the 2 groups after treatment,GGT and ALP hadn′t decreased significantly after treatment.Conclusions CMV infection can injure hepatocytes and epithelials on each grade of bile duct,thus CMV hepatitis causes intrahepatic cholestasis.Cholestasis due to hepatocytic impairment deserves emphasis and intervention should be done as early as possible.Gangciclovir therapy for CMV infection manifest effective and safe in short-term.

To discuss the influence of dexamethasion on lL-1β and TNF - α expression in suture - induced rabbit corneal neovascularization ( CNV ) and analyze the potential mechanism.
●METHODS: For 43 healthy rabbits, 40 were randomly selected for establishing CNV model in corneal stroma. The right eyes (group A) were received no medicine and the left eyes ( group B) were injected dexamethasone after successfully establishing the model. The no modeling 3 rabbits were normal control group. The morphologic change of corneal was observed with slit lamp microscope and the areas of CNV was calculated every day, then 8 rabbits were randomly chosen for sacrificing at 1, 4, 7, 14, 21d respectively. The pathological characteristics of CNV were observed after HE staining, and lL - 1β and TNF - α expression was detected by immunohistochemistry.
●RESULTS: CNV was grown at the 4d after suture, and the 7-14d was vigorous growth period. inflammatory cell infiltration appeared after HE staining, and CNV was located at the superficial stroma of cornea. lmmunohistochemistry results showed that lL - 1β and TNF - α expression was gradually increased with prolonged suture time. Compared with corneal stitch group, the rabbits cured by dexamethasone were found with less inflammatory cells infiltrating and neovescularization, moreover, the expression of lL - 1βand TNF-α decreased. There were statistical significance between the two groups (P<0. 05).
● CONCLUSlON: Dexamethasone can inhibit the CNV growth by controlling the inflammation of corneal and restraining lL-1β and TNF-α expression.

The objectives of this study are to prepare resveratrol loaded mixed micelles composed of poloxamer 403 and poloxamer 407, and optimize the formulation in order to achieve higher drug solubility and sustained drug release. Firstly, a thin-film hydration method was utilized to prepare the micelles. By using drug-loading, encapsulation yield and particle size of the micelles as criteria, influence of three variables, namely poloxamer 407 mass fraction, amount of water and feeding of resveratrol, on the quality of the micelles was optimized with a central composite design method. Steady fluorescence measurement was carried out to evaluate the critical micelle concentration of the carriers. Micelle stability upon dilution with simulated gastric fluid and simulated intestinal fluid was investigated. The in vitro release of resveratrol from the mixed micelles was monitored by dialysis method. It was observed that the particle size of the optimized micelle formulation was 24 nm, with drug-loading 11.78%, and encapsulation yield 82.51%. The mixed micelles increased the solubility of resveratrol for about 197 times. Moreover, the mixed micelles had a low critical micelle concentration of 0.05 mg · mL(-1) in water and no apparent changes in particle size and drug content were observed upon micelles dilution, indicating improved kinetic stability. Resveratrol was released from the micelles in a controlled manner for over 20 h, and the release process can be well described by Higuchi equation. Therefore, resveratrol-loaded poloxamer 403/407 mixed micelles could improve the solubility of resveratrol significantly and sustained drug release behavior can be achieved.

Pseudorabies virus (PRV) is a swine herpesvirus of the Alphaherpesvirinae subfamily and a pathogen of swine resulting in devastating disease and economic losses worldwide. Cre/loxP site-specific system has the character of site specific, time specific, tissue specific and high efficiency in recombination, which makes this system universal in vivo and in vitro recombination of bacteria, fungus, plants, insects and mammals. A recombinant PRV which contain a loxP site in TK locus by using Cre/LoxP recombinant system was construsted. A pair of primers were synthesized according to the pEGFP-C1 sequence published on GenBank, and were used to amplify the EGFP gene expression cassette with two loxP sites flanking each side. This target gene was cloned into pSKLR, the resulting transfer vector pSKLR-GFP-loxP was then cotransfected into 293T cells with PRV SH strain genomic DNA. The recombinant virus rPRV1 was selected and purified in TK-143 cells by choosing fluorescent expressing plaques. Cre expression vector pOG231 was cotransfected into 293T cells with rPRV1 genomic DNA. The second recombinant virus rPRV2 was obtained, which contains only one loxP site in TK locus. Sequencing results of rPRV2 TK gene indicated that 34bp loxP site was inserted into rPRV2 genome and there were 270bp deletion in TK gene. PCR amplifying different generations of rPRV2 TK gene showed that the mutant was stable when passages in RK-13 cells. TCID_ 50 assay indicated that rPRV2 grows well on RK-13 cells. The LD_ 50 test results on BALB/C mice suggested that the virulence of rPRV2 was reduced. As a conclusion, the report gene GFP expression cassette was removed successfully from rPRV1 genome and only one LoxP site was leaved in rPRV2 genome by using Cre/LoxP recombinant system.

Objective To refine the technique and improve the efficacy of seminal vesiculoscopy in the diagnosis and treatment of seminal vesicle disease.Methods The refined techniques of seminal vesculoscopy,using a patent catheter into the slit-like ejaculatory duct orifice through the verumontanum and another patent catheter introduced into seminal vesicle lumen,were performed in 58 cases,including intractable hematospermia in 42 cases and azoospermia in 16 cases.Results Seminal vesiculoscopy was successfully entered into the seminal vesicular lumen in 46 patients (79％) within 2-3 min.There was no obvious ejaculatory duct orifice in 12 of 16 azoopermia cases,and transurethral resection of verumontanum was performed,then seminal vesiculoscope was directly entered into seminal vesicle lumen.Symptoms of hematospermia were disappeared in 25 cases (60％),improved in 11 cases (26％),and azoospermia were cured in 6 cases (37％),improved in 5 (31％),unchanged in 5 (31％) during the follow-up period of 6-36 months (average 18 months).There were no major or minor complications in this series,and no urine reflux into ejaculatory duct in 19 cases demonstrated by contrast medium.Conclusion Refined seminal vesiculoscopy was technically safe,efficient,simple,and potentially widely used in the cases of hematospermia and ejaculatory duct obstructions.

Objective: To examine the effect of dietary behaviors on handgrip strength loss among the elderly, so as to provide insights into the prevention of handgrip strength loss. Methods : Based on the health surveillance cohort among the elderly in Zhejiang Province, two villages or communities were randomly sampled from each of Shaoxing and Zhoushan cities using a multi-stage cluster sampling method, and all residents that had lived in local areas for one year and longer and had an age of 60 years and older were enrolled. Participants' demographics, dietary behaviors, smoking, drinking, and exercise were collected through questionnaire surveys, and the height, body weight and handgrip strength were measured. The handgrip strength loss was diagnosed according the 2019 Consensus Update on Sarcopenia Diagnosis and Treatment proposed by Asian Working Group for Sarcopenia, and the effect of dietary behaviors on handgrip strength loss was examined using a multivariable logistic regression model. Results: A total of 1 265 residents were enrolled, with a mean age of (70.67±7.30) years, and including 565 men (44.66%) and 700 women (55.34%). The overall prevalence of handgrip strength loss was 42.85% among the participants, and the prevalence was 40.35% in men and 44.86% in women, respectively. Multivariable logistic regression analysis showed that nut intake for 1 to 3 times a week (OR=0.180, 95%CI: 0.088-0.367) and for 4 to 6 times a week (OR=0.241, 95%CI: 0.113-0.514) led to a reduced risk of handgrip strength loss among the elderly, and intake of sugary drinks for 4 to 6 times a week led to an increased risk of handgrip strength loss among the elderly (OR=2.298, 95%CI: 1.120-4.714) after adjustment for age, body mass index, educational level and exercise. Conclusion Intake of nuts and sugary drinks may affect the development of handgrip strength loss among the elderly.

Honokiol (HNK) is a small organic molecule purified from magnolia species and has demonstrated anticancer activities in a variety of cancer cell lines; however, its effect on oral squamous cell carcinoma (OSCC) cells is unknown. We investigated the antitumor activities of HNK on OSCC cells in vitro for the first time. The inhibitory effects of HNK on the growth and proliferation of OSCC cells were demonstrated via in vitro 3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and propidium iodide (PI) assays, and the apoptotic cells were investigated by the observation of morphological changes and detection of DNA fragmentation via PI, TdT-mediated dUTP-biotin nick end labeling (TUNEL), and DNA ladder assays, as well as flow cytometry assay. The results showed that HNK inhibited the growth and proliferation of OSCC cells in vitro in a time and dose-dependent manner. The inhibitory effect was associated with the cell apoptosis induced by HNK, evidenced by the morphological features of apoptotic cells, TUNEL-positive cells and a degradation of chromosomal DNA into small internucleosomal fragments. The study also demonstrated here that the inhibition or apoptosis mediated by 15 microg x mL(-1) or 20 microg x mL(-1) of HNK were more stronger compared with those of 20 microg x mL(-1) 5-fluorouracil (5-Fu, the control) applied to OSCC cells, when the ratio of OSCC cell numbers were measured between the treatment of different concentrations of HNK to the 5-Fu treatment for 48 h. HNK is a promising compound that can be potentially used as a novel treatment agent for human OSCC.

Objective To establish a mouse model of systemic C. albicans infection by oral inoculation of the pathogen and observe the proliferation and distribution of C. albicans in vivo tissues. Methods Male ICR mice(n=46) were used as the experiment group(n=40) and blank group (n=6). Cotton swabs with C. albicans were used to infect the mice (7 × 106 CFU/mL), and the blank group with saline. The mice of the experiment group were randomly divided into two groups:model group A for clinical assessment (n=20) and model group B for tissue fungal burden detection (n=20). Clinical score, survival and autopsy were carried out among the model group A. Five mice were randomly killed from the model group B at 3 d, 5 d and7 d after infection, respectively ( blank group killed 2 mice each time) . Microbial load tablet method was used to detect the tissue fungal burdens in different tissues, meanwhile samples of tongue, esophagus, stomach, liver, kidney, lung of infected mice were taken for pathological examination. Results White spot appeared on the surface of tongue since 3 d postinfection and increased with time and finally caused death. The mortality reached over 50% at 5 d. C. albicans was not only detected from the tongue (87?5%), stomach (87?5%), liver (54?5%), kidney (50?5%), lung (20%) and heart (4%), but also was microscopically seen mycelia proliferation in the tongue, stomach, liver, and kidney , yet not seen in the control group, showing that C. albicans caused disseminated systemic infection through mucosal infection in mice. Conclusions C. albicans can induce opportunistic systemic infection by breakthrough the mucosal immune barrier, so as to increase the infection to death.
